Sound design is an important measure to create a driving pleasure, a sound brand identity, and give feedback to drivers and the surroundings.

According to current legislative drafts (ECE R138), fully electric vehicles shall include a generator for synthetical sounds in order to warn vulnerable road users in advance.

Therefore, we created a real-time design system for driving sounds. It can play inside and outside sound and the independent overlay of up to ten different audio tracks at the same time.

To create new sounds we use realistic sounds from vehicle measurements, which then are enriched and edited digitally. Or, alternatively, we also synthesize the sounds fundamentally.

The right speaker system of course is also essential for the sound experience.

In order to adapt the designed sound to the vehicle and generate the best possible experience, we conduct the fine tuning of the complete system with the help of real driving trials and on our various test benches.

Furthermore, in close collaboration with our colleagues in the department User Experience we test the newly created sounds in test trials with testing participants.
